This is a $10 DLC or is available as part of the $20 Season Pass. The Shadow Forge is a blight upon the history of the Makers – a dark Forge crafted to harness the unfocused power of the Abyss. For eons it has sat abandoned, sealed off from the tree by the Makers themselves. But the hand of corruption has weakened the seals placed by the Makers, and the way to the Shadow Forge has once again opened. The Shadow Forge is a construct—a living machine of stone and metal powered by an old and powerful heart stone. When the Makers sealed the Shadow Forge away, they left this living machine to linger in isolation for thousands of years. In time, it has gone mad. Over those millennia, the Forge has built an army of powerful constructs – beasts not of stone, but of metal. Additionally, some small element of the Abyss has been infused in these form, giving them powers beyond those of a normal construct. The Forge plans to use the now opened portal on the tree to invade other worlds with his powerful construct army. Death must stop this.
